GRINDING-MILL FRAME.

SPECIFICATION forming part of Letters Patent No. 265,192, dated September 26, 1882.

Application filed April 510, 1882. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN P. WALLING, of South Edmeston, in the county of Otsego and State of New York, have invented certain Improvements in Grinding -Mill Frames, of which the following is a specification.

My invention consists in a mill-frame made in two parts, one comprising the curb and upper half of the supporting-columns, the other comprising the base and lower half of said columns.

The invention further consists in a novel manner of joining the two parts of theframe, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents an elevation of a mill provided with my improved frame, and Fig. 2 asectional view illustrating the manner of forming the joint.

Hitherto mill-frames have been either cast complete in one casting or formed of several distinct parts, requiring numerous bolts and braces to render the completed frame rigid and strong. The first of these plans, which I have practically employed, is objectionable because of the difficulty of producing the casting in a perfect condition, uninjured by warping or shrinking, and the second is objectionable because of the amount of work required in finishing and fitting the parts. By my present plan I avoid the'objectionable features of both of the plans above mentioned.

Referring to the drawings, A represents the frame complete, consisting of the upper section, a, composed of the curb b and upper half of columns 0, and the lower section, d, consisting of base 6 and lower half ot columns 0. At the point where the upper and lower parts of the columns meet a joint is formed, as indicated in Fig. 1 and as shown in detail in Fig. 2, by which a rigid connection between and a firm bearing of the upper portions of the columns upon the lower portions are provided and aneat finished appearance is produced." For this purpose the lower ends of the upper sections of the columns are formed with cup-shaped enlargements f, having a raised or projecting center, g, and the upper ends of the lower sections are formed with flanges or heads it, somewhat smaller than the interior of the cups, both the cups and the heads being perforated to receive bolts B, by which the parts a and d are united.

In setting upmy improved frame the upper through the cups and head from below, so

that when the iraine is turned right side up the finished heads of the bolts'shall be at the upper side. The bolts serve to center the heads or enlargements It in the cups fand to unite them firmly one to the other. After the parts are thus bolted together, lead or other soft metal or alloy is poured into the space t' and caused to fill the same, thereby forminga broad and firm bearing for the heads or enlargements h when in position, and making the joint exceedingly solid and firmi, so that there can be no possible movementof one part of the frame upon the other.

The details of thejoint may be modified without departing from the limits of my invention; but I 'prefer the construction described.

Having thus described my invention, what A the casting d, having the heads or enlargements h, said cups and enlargements being united, substantially as set forth.

3. The combination, in a mill-frame, of two parts, a d, as explained and shown, with a joint for uniting the said parts, the said joint comprising the cup f, having raised portion 9, the head h, fastening-bolts B, and interposd softmetal packing, all substantially as shown and described.
